we have a set of 15" baer rotors at the shop, for an impala. with either 6 or 8 piston calipers, so someone definately makes them. your best bet wouldn't be to ask someone on this site (no offense to anyone) about brakes, but to call wilwood, baer, SSBC, or another company that specializes in custom big brakes. i recommend wilwood, simply because i've installed a lot of wilwood kits, and have a set of their calipers, and they are located like 10 miles from my house. their phone number is 805-388-1188 and they have tech dudes and sales dudes... you just need to talk to someone that can recommend something for you. be patient and listen to their suggestions, after all they are the pro's that do brakes every day!
MBM makes a 1 1/8" master cylinder BTW... that'll help your volume situation...
